Considering it's per-developer:
Imagine an enterprise of 20 devs hacking away at various Xamarin projects with one dedicated "deploy" person. They'd get away with not paying licenses for 19 of those devs.

If said enterprise was so inclined they could share a valid license, or simply create new trial accounts every 30 days.
Organisations I have worked for tend to be pretty hot on their licensing obligations. Fines can be pretty steep.
You're assuming that current overly crippled evaluation model is good enough to show off your product -- I think the overwhelming consensus is that it is not.
Most software firms take licensing very seriously. I'm not sure it's worth crippling their trial offering just to try and deal with the ones that do not.
I think a much larger issue is the current (and onwards) generations of indies, enthusiasts and kids who are actively prohibited from trying Xamarin.
