Do you think it is ethical to (even if  ICBN permits) describe as New Species when a taxon (which you relegate to synonymy) has already been typified and described (no matter at different rank) and epithet could be transferred at specific rank without being rendered as later homonym or illegitimate otherwise?
With so many different opinions and approaches I think Botanical Code needs to be properly worded to help such situations. The purpose of Code is to ensure uniform interpretation and practice.
