Yes, that should simplify Matomo Campaign Tracking and Urchin Tracking Module URL parameters, but it will not be very effective against eBay’s free-for-fall approach.
So in this case, these are the simplified static filter rules:
*$removeparam=/^mtm_/
*$removeparam=/^utm_/
For eBay, they have a few URL parameters that can be targeted with this strategy:
*$removeparam=/^_trk/
*$removeparam=/^algo/
*$removeparam=/^ctx_/
*$removeparam=/^rk/
