I'm very aware about what you're saying. To put it differently in three points below.
1) The desire to change or not to change depends from person to person (there are even personality tests to assess stability for hiring people in jobs). Some people don't like change, other people like to change up to a point that they are very creative, artists etc..
2) You make a choice at the time of purchase, based on assumptions. If your needs change later on, it's your business, no one else can be responsible for your changes.
3) Camera gear, if taken good care, can last a very long time. It's a lot cheaper to settle on a camera kit and use it for a long time, even if the kit is expensive, as opposed to buying cheaper kits and changing often.
Back to my point, 645z / lenses is a proven camera but at the moment it doesn't seem to evolve, but if you know you won't need to upgrade it, it can be a good choice. If you want a MF system that's still evolving, the Fuji seems a better choice because more lenses are being added and there is more than one body to chose from.
The main issue I have with Fuji MF is the lack on long lenses , nothing beyond 250mm, unless using an adapted Pentax lens. Other than that, the Pentax 28-45 is a lot more expensive than the GF 32-64. If I would assemble a FujiTax kit, it would be with the Pentax 645 120 macro (because Pentax is 1:1, Fuji's 1:2), and some 400mm Pentax lens.
