it always fascinates me when somebody tells about something they do and ppl first of any other reaction spits out how they should do instead. Not interesting at all and often annoying if it isn't at least preceded by a "I find it interesting you did choose this approach, mind to share thenwhy and more details?" :D
debian is good as is, without flat/snap/fart things. If you are used to it then stick with it and you'll be happy and productive in everything you do, backed by a solid maintained os release process.
except in this case, where it looks like there are more than valid reasons
