That model works for the Jays because their core position player pieces are all "cheap", relatively speaking (Vlad, Bo, Kirk, Jansen, now Varsho, previously Teoscar/Gurriel, etc). It's probably a model that is not going to work the closer we get to 2025-26, depending on what happens with Vlad/Bo long term, but it was the right direction to take with the rotation for 2020-25. The alternative would have been doing what the O's are doing now, which is seeing year 1 of Adley's service time already disappear but having no urgency to build a contending rotation around him and Gunnar. They'd rather wait for internal options to start filtering up, and maybe that works eventually, but how long will it take if it does work?
Young position players + veteran rotation always seemed like the best direction to go in. It mitigates a lot of injury risk that comes with depending on young pitchers, and potentially expedites the ability to contend. The fact that they were able to get a legit ace with one of those FA contracts (Gausman) was a godsend. Hopefully in the next few years we see more internal development with SPs.
