I think it is important to constrain length to 200 bytes for this case
as here we receive a prepared transaction identifier which according
to docs [1] has a max length of 200 bytes. Also, in
ParseCommitRecord() and ParseAbortRecord(), we are using strlcpy with
200 as max length to copy prepare transaction identifier. So, I think
it is better to use strlcpy here unless you or Peter feels otherwise.
