Traditionally, people see two problems with these initializations:

the extra initialization may cause a performance loss.
the initialization might hide real bugs later on. For example, if an additional control flow branch is added which fails to initialize the variable, you don't get the warning anymore, not even from compilers which previously did a correct analysis.

Whether this is a big deal, I don't know.
