RSS feeds have a TTL inside the feed. Do feed readers respect it?

I would ask "Has a feed ever tried to abuse that to get readers to go away" the answer is yes, at which point the reader would ignore it.

I was just thinking a header with a suggested poll rate might be nice

The GitHub Event API uses a `X-Poll-Interval` header for this purpose. There is also Retry-After but that seems more targeted towards error states.

EDIT: There is the `Cache-Control` header, it seems ideal for this use-case
