Hi Julien, I agree. A New flag on the object header (WA Object, I assume that is what you are pointing to) where we have a flag to indicate if this is fixed (WSON) or flexi-grid is reasonable instead of creating a new object for a new Spectrum Assignment Object.
TLVs require a bit different encoding due to the nature of additional parameters for flexi-grid. So strict re-use of WSON TLV may not be sufficient for some cases in flexi-grid.

This I-D is very similar to draft-ietf-pce-wson-rwa-ext, which addresses the exact same problem over a slightly different WDM label space (running a side-by-side diff between them appears to be very practical). This new I-D requests the creation of one object and 3 TLVs, which are identical to the ones created in the WSON. As a result, I believe the latter should be reused as a starting popint. Covering the flexi-grid case may just need to allocate new flag in the object header to identify the WDM type we're dealing with, and document the flexi-grid-specific assumptions (if any).
