They now have portofolio of 16 active scope models (with subdivisions in BW added):

Part of the reason why the list is so long is just naming conventions. Defining DHO800 and 900 as separate families rather than just versions of the same product is a bit artificial -- the main thing it achieves is to create a clearer "hacking boundary" between the two, it seems, where additional encoders and maximum bandwidth are not easily hackable. Likewise with the MSO5000E as a separate model, which could also have been part of the MSO5000 lineup.

Another part of the reason is that they seem to never discontinue a product line. ;)

Again, I'd say its closer to 3 DHO scope lines, and that does not seem unreasonable. The naming conventions have shifted a bit; the product lines would normally be 1000, 2000 and 4000/5000 (in the prior Rigol portfolio or competing brands). But the decision to launch LA and AWG functionality first in the low-end product is very strange indeed...

These models are exactly that: different products.

800/900 are different products. Literally. It is not like they made 800 MSO with option to enable MSO. That would have been smart. But no, the made two different products. Case is different, BOM is different, FW is different. 
What I listed is literally 16 different production lines...
What about MSO8000 and MSO8000A? They are completely identical, but 8000A has bigger BW (600 vs 750 and 1 vs 1.5 GHz), even though it cannot satisfy Nyquist for all 4 ch for anything than base model..
Or MSO7000 and DS7000 ? Same scope but MSO deleted in hardware. I don't think difference in BOM is worth supporting two product lines.

Most manufacturers are putting in a great effort to NOT do this because it makes sense. No wonder they have problem finishing products and developing FW to maturity.

And you are correct, they are doing it upside down: they never stop selling old products but they stop developing FW (or at least drop it to very low level).

What makes you say that? There clearly is a platform strategy across the DHO 800/900, 1000 and 4000 software and hardware. Compared to the prior generation of products there is a lot of new development, transitioning to new ADCs, touch screens and OS. But the prior generation's architecture dates back 9 years or so, so that effort seems adequate.

They made new GUI for 1000Z/2000/4000 series.
Then they transitioned (completely from the scratch) to their 1st gen chipset and new GUI and touchscreens. That was 5000/7000/8000 series.

And they kept pretty much nothing from that for new DHO series. DHO series actually seem to run GUI that is something similar to their 70000 series devices.

Now they have active 4 generations of hardware:
1000D/E
1000Z /2000A
5000/7000/8000/8000A
DHOxxx/xxxx

I really don't know if that makes sense at all, and I'm afraid the Siglent is going to be quite a bit more expensive, and might not be easily hackable, maybe oriented at a different market.

Hmmm, mine arrived without options but has all now.  >:D

I think you are too generous.  "Developing" would imply good industry practices like a solid software release management process, including a consistent release cadence, useful release notes, proper attention to package verification and the correct application of semantic version numbers.

Based on my experience of Rigol FW/SW updates so far, I'd say "farting out software" myself.
