Yes.  The MELPA release has been deprecated for Emacs 31+ since this commit
https://github.com/LionyxML/markdown-ts-mode/commit/801579b9b955f63673dd6dc9742c1fd5311b76c9

Perhaps someone I cc'd (or someone else) can recommend a good/best way to
handle sharing a configuration across pre 31 and 31+ where 31+ will use the
built-in package and pre 31 from your 'package-user-dir'.
