And they are a simple easy option for relatively new teams for omindirectional movement. Swerve requires a lot of resources, and frankly with a few sacrifices, mecanum is right up there with them...

The strafing speed is one issue. The bigger issue for me is they are worthless against good defense and also cannot provide solid defense either. I have seen too many strong offensive robots be shut down this year in particular as soon as defense is played on them.
Another huge issue I have is that the majority of teams do not program them to be able to take advantage of the few benefits which makes them even less beneficial. Way too many teams drive mecanum robots like a traditional skid-steer robot and only strafe occasionally or never at all. In my opinion, mecanum wheels are a compromise of all things and don't excel at anything.
