Actually RFC 3548 defines a "url safe" base64 alphabet which substitutes -

I did not know there was an RFC for this.

The RFC is marked as "Informational", so how widely used is
the URL-safe base64 encoding used?

Nothing is currently listed in the IETF assignments for this
type of encoding:

I have no problems going with it, as long as it is documented.
However, from a usability perspective (possibly), the use
of understrike can be a problem.

For example, links are normally rendered with an underline, and
this rendering behavior can "hide" an understrike character, making
the URL appear to have a space in it.
