There has been no change to commercials afaik, deployment was never a thing and morale did not matter for them.
As for recreational modules vs colony/orbital, it is much easier (and cheaper) to plop down a small station with Recreational module than a huge (and expensive) orbital. Ideally you can use your orbital for shore leave but it is not always possible... and not everyone uses Orbital habs.
Deployment is 3 months, no need for more or less.
