You are more free with your choices for placement of explicit rules in make 
(because you can not and will therefore not cancel them).

You should be careful then which of your explicit rules will be configured
for the use as the default make rule.

Bigger freedom for positioning of explicit make rules.
Have you got any preferences there?

The clarification for the mentioned distinction might be finished in principle
for now. But I guess that the discussion will be continued around the handling
of “optional” input files (and their effect on the usage of static pattern rules
and suffix rules).
