Actually if penals lost access to satchels and ptrs upgrades if their t1 is lost, that would be absolutely fine. Even preferable.
But remember penal ptrs and satchels weren't made by relic devs. It makes sense there's discrepancies between the designs.
Relic implements the changes and have full responsibility for the them.
Penal had satchel and flamers before that patch but they did not lose access to them when T1 was lost, neither do conscripts lose access molotovs and AT grenades if they lose the base building.
Discrepancies that serve no purpose should be removed.
This is quite irrelevant to OP, so lets try to get back on subject.
