Doesn't matter. The point is that extra features that may not be strongly related to the core function of a piece of test equipment can be useful to some people. It is foolish to dismiss such features.
Not if your goal is to focus on what matters in a core product.
When you do product research with customers (which they did) you'll get literally every suggestion including the kitchen sink.
The art is deciding what's really important and what you should focus on.
Just so.
It it usually better to do one thing well rather than two things poorly.
There are exceptions, where it can make sense to put two adequate things in one enclosure. But those tend to be very specific special cases.
Like multimeters? I don't know, those are kinda popular...

Joking aside, it really depends of what is adequate for certain job. For instance, if all you want to check if CPU crystal is oscillating at 10MHz and accuracy is not critical, scope internal frequency measurements are more than good enough. I also never bought timer/counter (I have counter) because I have a scope that has timing measurements that can go down in picosecond resolutions, with added benefit you don't fly blind...
Good 12 bit (or more) scope will be a good sampling RMS voltmeter with very large bandwidths... So I never got that specialized RMS meter..
I don't need to do any of these measurements to a calibration lab level, and really outstanding specialized instruments are not justified for me.
Modern scopes are next step multimeters.
And today's scopes can actually do many things well, if done right.. Of course, there is no need to put a TurboTax on a scope....
There has to be a focus as to what it is.
