Sure.
That's why advices are "graded" from info to error in the current
preliminary version.
Advices that may or may not be good depending on undecidable elements
have a lower grade. For instance, most attributes should be "NOT NULL"
from a statistical point of view, but it is perfectly legitimate to
have nullable attributes mostly anywhere, so the corresponding advices
is just an "info".
