Having read that thread, and given the one and a half years since the
original report, this doesn't look like a problem that should block
the release of Emacs 26.1.

Thanks.

It was already reverted from the previous release branch because it
wasn't considered suitable for a release. Personally I think allowing
two dir-locals (as it is now) is just not a good idea; and it's not just
me, eg http://lists.gnu.org/archive/html/emacs-devel/2016-01/msg01581.html

Anyway, the plan was to improve it for 26:

    We can also just revert it from the release branch for the moment,
    and postpone it until emacs 26 while we settle on a preferred
    interface/implementation.

Nothing's happened since then AFAIK.
But I don't have anything else to say on the issue.

There's no interest in addressing this issue. Closing as wontfix.

I was going to take a look at this for Emacs 27, improving build times
is of interest to me.  Though the bug thread here is a bit unclear, it
talks about the wildcards being the problem, but then weren't the
general wildcards replaced with the more limited dir-locals-2 thing?

Feel free to reopen if you would like to work on this.

Thanks.
