There are risks associated with all the options, there is no 'safer' option, atm. Just different ones.
If the infiltration rolls had been worse, less allies found, less stealth managed, less intel gathered, then Natasha would have offered different opinions, such 'possible, but very dangerous and would really prefer not to' or 'don't think it's a good idea at all, need more time' or even potentially 'need extraction immediately we have failed intelligence objective' or the like.
AT THE SAME TIME, there are still dangers like, yes, them poking at the newer slaves and the like, but that could be true for either option. They could figure it's Natasha and come for them, they might figure it out, they might chase them in the next aquafarm over.
They might not, they might put notice out, they might figure them out or might not figure who it was, they might follow and chase them during extraction, they could do a number of things.
The enemy gets a vote too, is all that can really be said. The other people on the board get to make their decisions. Fog of war is in effect for multiple sides here.
