That's a good point, Dave. For those who've never run into the FAA inspector with an attitude... the seat belts must be identified with mfr. data and TSO cert. basis. This is many times simply a cloth lable sewed onto the strap, and it wears/tears/disappears. Result: Seat Belt no longer airworthy.
But actually removing the tag is not the solution because that technically condemns the belt. (I understand the intent tho', Dave.) If your tag is accidentally removed, a seat belt re-manufacturer can re-man your seat belt and re-attach certification data-tags. Without the tag, most mfr's will refuse the job and require you to purchase new belts. ($$$)
The metal tags were intended as a more durable solution, but they are subject to damage, cutting, tearing, because they are made of soft aluminum and become unuseable when jammed by the seat/track.
I solved the problem on my Baron when I had the belts re-mfr'd by having the tags made of durable vinyl instead of metal. The data was "burned" into the vinyl tag like a branding-iron. The mfr. was Aircraft Belts of Kemah, TX. They will re-mfr your belts....or make a new set of any color you wish...using yours as a model and certification basis. Or they'll simply make you up a new set if you prefer.

Meanwhile, back to the 170: I simply educate my pax to do like I do. Don't slam the doors. Let the pilot operate the doors. .... And when I unbuckle my belts...I immediately simply bring the buckles beneath my thighs and re-buckle them together ... and leave them on the seat. That way when I re-board... I'm sitting on them...and all I have to do is reach beneath my thighs ..unsnap them..and re-snap them in my lap.
