Well of course, how else would you trick script kiddies that figured out when they DDOSed 127.0.0.1 and learned what a loop back was, and get them again in a few weeks with "ok ok my real address is 127.34.21.2"

Wait... I know 127.0.0.1 but what's the second one?

not sure if you are joking, but any valid IP4 address starting with 127. does the same thing, loopback. 127.0.0.1 is just the standard most people use, you could use 127.127.127.127, or 127.1.1.1 or any random numbers 0 and 254 for the second 2, and 1 and 254 for the last and the effects will be identical.

In fact, it's so standard that there's a bunch of shitty code out there that thinks 127.0.0.1 is the only loopback address.

I'm thinking of a networked Chinese laser cutter that we put on our 10.0.0.0/16 network in the makerspace. It seems to think that 10.0.1.1 and 10.0.2.1 are on different networks. Wouldn't be surprised if it does a similar mistake with loopback addresses.
