No, I do not see anything here that would benefit from "throwing money at it." To accomplish their science objectives, data scientists have many options, of which "Perl is only one of now-many." The scientist's obvious (and only) goal is to get to their finish-line of an accepted publication, not per se "to use Perl" to get there. Anyone who needs to know about PDL already does, and if they elect to use it they will do so without (financial) provocation. The Foundation should keep its money in its pocket.
