This is a good precaution. I try to force myself to use the VM for such things as much as possible but somehow they always end up inside my main OS.
I prefer to do it without learning the hard way
The same for LN wallets: I've tested many of them on Android, but never on my daily use phone. Most of them are on a tablet now. I always start small, but somehow balances tend to grow when I add more of them. I try to keep it under a hundred bucks per device. It still sucks to lose it, but it's a risk I can accept.
I've also used old phones (I guess everyone has a pile of those nowadays), but the broken screens and lack of memory make them hard to use.
