[asterisk-dev] new priority of pattern matching in 1.4. Does it makes sense?

That's contradictory; defining 'best' means patterns have different weights.

Asterisk has always optimized the pattern matching process to avoid
having to search in included contexts and (especially) switch statements
when it can; doing otherwise would mean building a list of all
*possible* patterns for this lookup and then weighing them all, which
could be quite expensive and wasteful if the pattern that ends up
matching is the one in the first context that was searched.
