My understanding is that the dry glue on the spare won't bond much with the dry glue on the rim much right away, so the main force holding the tire on is the pressure. Get a second flat, and the tire may roll off.
This is concerning on a technical ride, and I wondered if adding tape and then mounting the spare would give a better immediate bond?
There is another option - if you’re worried about flatting. There are tubeless tubulars from Tufo and Donnelly/Clement that can be filled with sealant and repaired with a plug system (Dynaplug etc...) like clincher tubeless. Not only would this be less likely to flat, the repair can be on the order of <1min for most repairs and not require removing the tire from the rim.
