delete api date time resolution for snapshots

[sudo-su-tony]

First off I'm very new to Elastic, currently running open distro, but I tested this on normal Elastic too.
I was trying to delete snapshots using the delete api with an expression something like this

DELETE _snapshot/my_repository/%3Cname-%7Bnow%2FM-1M%7Byyyy.MM%7D%7D%3E

and it would return:
[my_repository:<name-{now/M-1M{yyyy.MM}}>] is missing

which means the api didn't resolve the datetime expression I think.
I no longer need to do this (turns out it was a mistake anyways), but I thought I'd report this in case it's unintended because I couldn't find anything relating to it on google.

Hi @sudo-su-tony

thanks for raising this, it's a good point and fortunately known.

Currently, deleting multi snapshots in one go is not supported so there's no support for any kind of expression here either. I'm currently implementing deleting multiple snapshots at once as a new feature in #49800 so some form of this is eventually incoming.

For now everything is working as intended, so I'm closing here as we already have #49800.
