If these compilers provide reliable testing, running several times a day,
they will deliver their results regardless of whether they are the only ones
in the list.

Trimming the list will not increase their reliability, it will just decrease
the reliability of the compilers that are left off the list.

In short, I believe that this is a step backwards. It does enable us to get
a release out that doesn't work on an important compiler that is not on the
list. Is this a feature?
