It's important to remember here that Jed Hoyer took over the team at the end of the covid year, 2020, at which time Ricketts was claiming 'biblical' losses, the team was coming off a technical playoff appearance, and really, things were just weird big picture (the biggest offseason signing across baseball was George Springer for 6/150, only three players got over 100m). His two significant signings that year were Joc Pederson (28 years old, 1/7) and Arrieta (34 years old, 1/6). It was very much a 'one last run with the core' season, and we all know how that went, but my bigger point is that it was a strange offseason, no one was totally sure what 2021 would look like etc.
2022 was projected to be, and ended up being, a very bad team. No real point in signing veterans, and no real point for the veterans to want to sign here. Of the signings going into 2023, still very much considered a bridge year, Taillon, Smyly, Mancini, Barnhart, Boxberger, Hosmer were all in their 30s.
All of this to say that we really don't know what preferences Hoyer has based on past performance, because he's never ran a team in the middle of their competitive window. No one really thought too much about Imanaga because we were all focused on Shohei and Soto, and I assume absolutely no one saw the Busch trade coming.
