Not for months and months. First trial supposedly tuned to an entire party of 7* units was Gilgamesh Runback, released 3 weeks ago. JP is 7-8 months ahead of GL. The jerk-off over 7* power jump is just bored players looking for stimulation, not something required to clear content.
This is the real trial, of course, despite people pretending otherwise. Keeping up with the Joneses, feeling inferior to stacked friend units, et cetera. Nothing wrong with tapping out if you're losing this particular fight, but it's very distinct from the former.
For you and anyone else keeping track, if you are susceptible to this, you are going to be in for a bad time when STMRs drop.
