Licence restriction via regular expression #9

Describe the solution you'd like
Licences often have many versions of their text. For instance GPL counts 19 known licence versions ranging from GPL-1.0 to GPL-3.0-with-GCC-exception according to SPDX.
Although it is possible to list all restricted licences exhaustively, it feels cumbersome and does nothing to prevent future versions from falling through the gaps.
It would be great to be able to support regular expressions so we can express the restriction in a more generic way - e.g. -r MPL* to restrict all MPL licences
Describe alternatives you've considered
Support for restriction based on semantic versioning doesn't seem workable, given that some licence identifiers do not follow that convention.
