IIRC, Ilya Z has said that qr// compiling immediately instead of at first use is an implementation detail. According to that view, qr// is a request to define a resuable regex, not to compile one.

And the key part of reusability is having it maintain it's own flags; Regexp::Common would break seriously if the external flags leaked in.
