I would say all the aspects that you find lacking with the way Vim is developed, in my opinion, is what makes it the stable, powerful editor it is today.

It is somewhat following the linux model (with Linus as the primary developer in the early days).

Just like linux, I believe this has added to the widespread popularity of Vim (ie. it is available by default on most distributions).

Vim doesn't need to "modernize". I would say its availability and ability to still stay relevant is more modern than most other open-source software.
