Yes is the simple answer, it releases the sears of any tension so improving feel and connection.

I found the crinkle washers gave the sears too much lateral movement as they were only 0.4mm thick...
I measured the internal housing at 4.75mm deep and the sears a 3.00mm so in my case there was 1.00mm of movement, which doesn't sound much but it is 33% of the sear!
I replaced mine for stainless washers to tighten the tolerance..
I have also made and fitted a spring guide for the trigger weight preload spring to stop it buckling and catching the inner housing..
All a bit anal but I like faffing around
