No for small amounts of wear the real issue is the slackness caused by a longer chain. That's why singlespeed bikes have had tensioning mechanisms since time immemorial.

Chains are vulnerable, expendable, replaceable, and inexpensive.
They're really not that inexpensive. Sure the cheap bottom of the barrel ones are cheap, but a decent chain costs more than some entire bikes at wally world and they have much longer usable life spans than the profligate chain wasters like to admit.
As it is written:
"The end of all things is near. Therefore be clear minded and self-controlled so that you can pray. Above all, adjust each others chains tightly,
because tension covers over a multitude of sins." 1 Peter 4:7-8

You just sandwich the spider between them, line up the holes, and put in the bolts. Same way you attach a chain guard (you might need slightly longer bolts).

That's funny because over the years I've taken about three links off the chain on my primary bike due to stretch and it's still going strong. Although it's started making nasty popping and grinding sounds after this last winter, I wonder if it will ever die.
