that's not a very nuanced take.
I never pretended to propose a nuanced take ;)
But without telemetry that reports back the version of the app in use it's impossible to know when it's safe to do so.
You can communicate with your users. This is what I do with my own software, and it has been working very well for the last 10 years.

If some users were bothered by that, none were bothered enough to actually tell me about it.
