It's always best to supply at least AST_FRIENDLY_OFFSET bytes of space
anyway, in case the consumer of your frames is not who you expect it to
be :-) It is also possible that a translator could modify the data in
place on an existing frame (although I don't think any of our existing
translators do that, it's within the rules as best I can remember), so
you can't even be sure that if a translation path is in place that it
will be creating new frames from yours.
