This is unnecessary.  All the rule does is limit the process to class IN zones.  UPDATE, IXFR and AXFR are class agnostic.

1.  TIMEOUT resource records are only defined for CLASS IN.

This seems overly restrictive.  I would allow TIMEOUT records that
match added records to be accepted.

5.  TIMEOUT resource records cannot be directly added, modified, or
       deleted through DNS Update.

Secondary servers that are TIMEOUT aware should ignore TIMEOUT records
beyond storing them in case the server get promoted to being the master.

Is the secondary going to be able regenerate the RRset as the records are
removed as well as generate and sign NSEC and NSEC3 records?

Sources of TIMEOUT Expiry Time

Add matching TIMEOUT records added via UPDATE.
