That is true, but no one wants to rely always on MG. Hopefully Pzgrens come on the Infanterie Kompanie or After Battle Phase 1. Since there is not any clear resolution for Grens.
Its still nice to at least have an MG to rely on.
Tbh I'd like to experiment with a new vet 1 ability that gives grens slightly more accuracy against suppressed models to synergize with the mg42 and be able to better punish blobs as a pair. The mg42 is a fantastic weapon but we lose dps when it's commanding an area due to the modifiers of Supression. Might not be quite what you are looking for but ist is designed around combined arms, the beautiful new vet ability for pgrens reinforces them as mechanized infantry, it would be nice to see grens amp up their ability to support their star weapon team a bit better.
