Thanks, that is excellent, so I don't see any reason not to add those to the motor record.

My mistake.  This commit adds "prop(YES)" to the base .dbd files.
The C .dbd file parser has always ignored unknown recordtype "items".
(cf. dbRecordtypeFieldItem() ) so I think any 3.14 would ignore "prop(YES)".
