The stronger the spring in it, probably the better, or yeah, get rid of it altogether.
Not sure if that is what you meant but not using a spring (and yes you want a strong one) would definitely allow the adjuster to drift out of tune. That's precisely why those spring are there in the first place anyway.
BTW, regardless of front or rear, they both see more movement then you'd give them credit for really.
Especially so while downshifting a few cogs at once which temporarily releases the cable tension allowing the housing to move up and down as the derrailleur tries to catch up with the slack.
