Ah well. I turned 3 `mapcar' calls into a single one. It should,
hopefully improve speed in your case (could you confirm it).

Also, I suggest to signal the deprecation in ORG-NEWS (old timers read
it, right?) and remove this part of code during 8.4 development.

WDYT?

Org Lint is not in master branch, yet.

The problem is that linting is not exact science. You shouldn't put too
much trust into it.

Also, "version" too broad: despite its name, some syntax changes were
introduced in the middle of "8.3beta".

Therefore, I'm not sure it's worth the hassle.
