I would have thought it was in any airport operator's SOP to do a runway (indeed, taxiway too) inspection if an aircraft reports they have had a mechanical problem. Anyone knowledgeable will be aware that if you have such a problem there is a reasonable chance of at least lubricant being deposited, and indeed debris as well.
I'll bet if you report any engine problem on the runway at CDG nowadays they will be straight out to have a look.
