is that really an issue? if so, is there anything special you do to prevent it?
There should be no issues with that at all. I've been doing it for a living for 22 years with zero problems. Personally, I do not bother with a plug unless the hole is 1/4" or larger.
People have good luck with the plug patches, but I've not used them very often.
