Honestly, I've been following along with these trends a lot and it seems like the answers for 1&2 come down to team size. If you have a bigger team, with more development inertia microservices can seem amazing and the tradeoffs are worth it (repeated work vs. development tempo).

To a small team that doesn't have the inertial issues to generate the benefits of microservices, it seems like they are nice in theory but have too much overhead to supplant monolithic approaches.
