Actually should we initialize this too?

yeah good point, I guess that PARAMETER_NOT_SET would be a good default. Not sure how we refer to message constants from another msg file though.

My reasoning for not putting a default for this was that, while all-but-one of the _value fields will be unused, the type is not "optional" so the client library should always initialise it itself

Should we open a ticket for this somewhere (rosidl?) that would be a useful feature

I've got two thumbs up on my last comment so will consider this question resolved. (in the future, reactions don't send notifications (at least not to me!) so comments would be appreciated)

👍 sorry forgot about that, yeah it would be great if github allowed to enable notification for "reactions"
