Airborne talcum type dust is not a problem at all for the dust wipers and oil seals underneath them. The fork gaiters need breather holes to be able to stay attached to the fork leg or brace. (I think your Velcro is 'course enough' to vent.)
Problems arise with dried sticky type mud, dried bugs or gravel nicks from exposed fork tubes. (Rotten boots) All three actually can make 'minute cuts' in the seal lips, causing leakage.
All seals will eventually just wear out, requiring replacement.
Modify at "YOUR OWN RISK"!
