You'd think the cap would be on (evasion-tracking), not on evasion itself. So you can't stack evasion to be literally untouchable, but you can stack evasion to counter tracking.Small differences in combat formulas have such huge consequences on overall balance.
Not a great idea as it would make corvettes even more batshit than they are.
Also, something I discovered today, which there seems to be some confusion about, is shield regen in combat which is definitely a thing, even without shield capacitors. You can observe it the first time you take out a pirate station with your starting corvettes. The thing is that a ship needs to go a few ticks without being attacked to start regenerating, which means it's going to be marginal in most engagements, but when using monofleets where enemies are liable to switch targets a lot you might see a small benefit when ships are left alone for a bit.
