john, there is no default or recommended behaviour described in section 4.3 of 
the bundling i-d,

now, if one assumes that, by default, component recording (only) must be 
provided, there is no possibility to deliver the expected feature as the 
components selected on a link local basis would be unknown to the ingress,

also, there is more complex problem that even if you assume for instance an 
bundled link and record two subobjects of the form <router_id, interface_id> one 
for the bundle and one for the component there is an ordering rule that should 
be define to link the associated label subobject if present;

i hope it clarifies that 1) there is something to be addressed, 2) mechanism 
proposed is one possible way to address it 3) intend was to make the default 
behaviour of recording at the same level than ERO and trigger additional 
information using this flag (the equivalent of label recording btw)

thanks,
- dimitri.
