Sure I can see it happening if you tag it to an ultra light vehicle that has to exist in an environment where faust is everywhere 
But more seriously Allies have nondoc equivalents with mortar flares, improved infantry sight (pyrotechnics) and USF get out of jail free card with more smokes than anyone else and yes Major recon.
The sole reason the Kubel kept it's cheesy maphack when it still received passive vet, it's because the unit never got meta status and it's there to give some sort of diversity to OKW early on. Although it's generally hard to justify the attention investment the unit requires compared to simple use another Volk.
It would had been the first thing to be changed/removed or put in line with other similar abilities, both on Allies and Axis side (tracking, vehicle detection, infantry awareness). Basically limited duration and munition cost.
In regards to changes to Kubel, what if:
-Vet 0 Stealth detection mode: -25% speed +20 camouflaged detection +10 sight (current is -50% speed, +20 camo and minimap up to 70 range)
-Vet 1 20s 15 muni for 70 range minimap info
-After a truck is deployed, the unit self repairs when in allied territory, not having received nor moved after X amount of time. Doesn't remove snares criticals on it's own.
-Remove self repair at vet 3 and passive suppression/RA at vet 5.
-Move vet4 offensive bonuses to vet 3
-Vet 4 give it some small armor like +1
-Vet 5 give it a similar ability to suppress like the 250 HT. Reduces speed by 95% (so it can rotate but not cheese move around) and size by X and gives a small amount of suppression. Give it a munition cost if necessary.
