I share your dilemma as was hoping to wait for the SS Vector but no signs its resupplying anytime soon so went a different direction solving my SE itch. Similar with the Blue Devil balm that looks to be out of stock
Seeing as there is no longer a P&C endorsed Sabbatical I'd say its up to the individual on how strict they want to be as some might go with no purchases or any kind, others allow swaps, charity acquisitions and some might grab a new item and keep it locked away for the year...
Nobody's going to know either way unless some cheeky bugger questions it during a SOTD post which kinda reminds me why we no longer have endorsed Sabbaticals.
Shoot me a PM and I'll look to get the Vector out your way before the holidays and hope to see you on the 2022 Sabbatical bus...
