Yeah, if upstream isn't shipping this as a proper library i'd try to get
this in as either a copylib (guidelines for that already exist) or as a
code snippet (guidelines for that don't yet exist but the fpc has recently
granted several exceptions based on the concept.)

It still needs to go through fpc to grant the exception for two reasons: 1)
confirm that it is in fact a copylib or code snippet 2) to assign it a
virtual provide so packages that bundle it can be notified in case a severe
bug is discovered in the porter stemmer upstream on which these are based.
