Maybe because they won't get one-shotted
No idea why obers were overnerfed. No idea why basic infantry has the best AT. No idea why the sweeper range is short. No idea why Jagdpanzer can cloack.
See though, there's a good reason to say why
not.
The part where their unit is described as "light infantry", a term generally applied to a higher quality/lower availability unit to that of more standard infantrymen. That being said, I think the term was more of an honorific applied to a specific regiment than an distinct tactical unit, but nonetheless they would be troops that, in the grand scheme of things, are rather rare, unlike the Volksgrenadiers they outnumber.
But yeah, I have no issue with their actual in-game effectiveness...and it's nice not getting one-shot. Please fix that matter, Relic.
