Language flags (css classes and sprites) got removed in 7.6.0
According to the commit message of issue 70477 some deprecations take place for v7 LTS via 7.6.0
But this commit does more than a deprecation because it also removes files
And it also removes a bugfix which was merged with 7.4.0
I'd be happy to still be able to support 6.2 with metaseo extension and move to IconRegistry as soon as we drop support for 6.2.
Our old 6.2-style code is missing css classes for language flags and therefore only displays a red X icon.
We're using the css classes for flags in the backend.
I guess 58c46d75099acd8449aded959efe8f031cec13d0 must at least be considered as a breaking change the way it was done. Is that intended or is it a bug or was there a breaking change in the past (pre-6.2) which allows for the removal of the files?
Removal of flags.css and flags.png was suggested by Wouter Wolters (with a question mark).
A breaking change was suggested by Christian Kuhn (with a question mark) for Patch set 7 of https://review.typo3.org/#/c/43897/ But no breaking change was communicated.
I'm not sure if that was a breaking change, a bug or totally fine. Please give some feedback which was the intention here. For the moment it looks more like a bug to me, while I'm aware that there is a modern alternative in 7.6.x.
Suggested fix would be to give back the dropped files, css classes and bugfix 68217 for 7.6.x only.
