I believe the more serious collectors wouldn't alter the rifle in any way. If it was really risky as far as cracking, e.g. a .458, they'd likely opt to simply not shoot it at all.
I don't think you are implying you believe the fore end screw carries much recoil to prevent cracking the stock. If you are, then there are the Featherweights to consider. But perhaps FW rifles are more prone to cracking than standard rifles? I dunno.
Ross Seyfried wrote some things that led me to believe one of the reason Pre '64 rifles were usually accurate was the fore end screw. I believe he advocates tightening it firmly, but not "farmer tight." In the modern age, we seem to prefer floated barrels. Simply removing the screw without floating the barrel, or barely tightening the screw, seems to me to be a bad Idea. But some here seem to say it works pretty well.
Go figure.
