Will it ruin a blower's future-adjustments to do the 'H & L screw-hack'?

These 2-strokes have H & L adjustments on the carbs but often have limiters built in and commonly people just hack a line across them to adjust with a flat-head, I’m tempted to do this but, at the same time, almost every-last-unit I own (from blowers to saws to everything) seems to have the same type of splined-adjustment threading, am getting the impression it’s just 1 tool (not 1 tool – per – brand!) in which case it seems you can order them from china for $1 and using a saw on such a delicate part of your carb would just be foolish!
Thanks 🙂
