pylint #83217 Identifier name restrictions [open]

pylint does not recognize identifiers that are shorter than 3 characters.

I get the error:
Invalid name "db" (should match [a-z_][a-z0-9_]{2,30}$)

It is reasonable that very short names should cause some sort of diagnostic, but that diagnostic should not be that an identifier is invalid when that's not true.
