Is the fund applicable to financing ongoing triage for projects? Nope.
Is €30k worth of funding for 40 kicking off individual projects valuable and worthwhile? Hell, yes.
Might the scope of an endeavor like this evolve in coming years, as they demonstrate success? Sure.
Government backed funding for OSS projects is a really smart and efficient use of public money when it comes to investing in digital infrastructure. It doesn't need to be perfect on launch, and it's far easier to pitch and justify the value of seed money like this, than it is to make (just as valuable, but more subtle) wider case for ongoing funding.
Furthermore I'm sure there's plenty of projects that could pitch proposals for new features that they want to build, while building in the cost of ongoing triage during those 6 months. (Ie. Make sure that the amount of work your proposing is viable on the assumption that you'll also have ongoing triage work to keep on top of at the same time.)
Let's celebrate the OSS funding achievements as they come, rather than knocking them.
