Current Debian stable bullseye has Emacs-27.1, for oldstable the same 
version is available from buster-backports repository (I have not tried 
it though) https://packages.debian.org/search?keywords=emacs

Debian supports upgrades between stable releases for more than 20 years. 
Problems may originate from third-party repositories or e.g. when binary 
format of some tool changes (e.g. PostGIS plugin for PostgreSQL). 
Certainly support of some legacy hardware may be dropped in new release. 
Manual actions during upgrade may be required but I would not call it 
nightmare.
