How do you mean?
I only find that feature for ‘loud noise’ and there’s also only speed of switching. But that doesn’t impact recognition of other environments, only if the transition between programs will be slow or instant (when it’s instant people complain about hearing it, while I complain when it’s slow, so mine are at fastest).
I’d say, mostly yes.
Because it’s full of hint buttons and then you google if some term isn’t clear, then you get results from audiology.com, this forum or manufacturer published articles. Or you just ask here directly.
And you learn item by item.
Then you compare two sw and see how it’s all the same, just maybe different names.
And then you wonder why so many fittters whine how it’s hard to fit many manufacturers, have no clue what they’re doing, and conclude that they’re not worth your time and money, that you don’t want a seller but knowledgeable professional with proper equipment.
And you find one and you cooperate with them, while doing some tweaking on your own, like changing the speed of transition, more or less noise cancelling and so on. And you spare time for both sides. I always keep my fitter in the loop about what I’ve changed and he always download latest setup from my HAs first.
