All extension branches were removed during the migration to Git. Very few extensions have branches for MW core major version support. There's no longer a simple way to branch all extensions when a core release is updated, and nobody has volunteered to write a script.
So we're back to the situation we had in MW 1.9 and earlier, where it's usually not possible to run any actively maintained extension against an MW core that's not the current trunk.
Given this, I think code reviewers should insist on backwards compatibility with MW 1.20 for commits to the master branch of extensions that are commonly used outside Wikimedia, at least until the release management issue is solved.

I've always been in favor of the trunk/master of an extension retaining compatibility with the latest stable version of MediaWiki until our next release. (with brand new extensions designed around new features in alpha an exception)
However our LTS support for 1.19 is going to make this more of an issue.
I made quite enough of MediaWiki freelancer work for small to medium MediaWiki installations here in Russia. Most of owners want new extensions or new functionality in old extensions and rarely want to upgrade the core. They consider that "core update is too expensive". It was especially true for 1.17, which introduced a lot of client-side changes. Maybe someday the most of activity (like Wikidata, Parsoid and so on) will be outside of core? Such way core might become smaller part of total project and change less often. Dmitriy
