I agree. The package is what matters, the library that comes from is
unknown to most people anyway. It is only a hint as to what to expect.
The start of the library name doesn't really give you any hint at all.

Perhaps some people aggregate all of the different "Packages" and
"Val" combinations there are to roughly determine the number of reels
they'll need to use on the machine.

If no-one objects I'll commit the change for you.

Best Regards,

Brian.
