Cost and complexity is likely why single lock knob/lever was not done on the 45N-2. IMO, as a light weight field folder rear camera movements are not often used and the majority of images made does not need this camera movement. Not designing and offering ease of implementing rear swing is an acceptable trade off given what the majority of users and image making needs are for a field folder.
One other factor to consider is user experience, skill level and demands placed on any view camera. For those new to view camera, setting up to make a basic image is challenge enough. Add the complexities of view camera movements adds greatly to this challenge. For many new to view camera, there is incentive to not use camera movements as it can add greatly to the challenge and complexity. For those who spent hours upon hours using a view camera in-studio and in image making demands which require pushing any view camera to the absolute limits of their movement capabilities. For those view camera folks using a view camera in this way with these demands driven by image goals, lesser view cameras are not gonna work.
If considering a Sinar F2, know many sellers do not know the difference between a F, F+, F1, F2 early and later versions. Many sellers ad media their Sinar offerings with mis-information and not knowing the differences between Sinar F cameras with all their variants over their decades of production.
Basically, the F2 has focusing on the front standard and the base of the the rail attachment is different. All F2s have a wrap around rail clamp that slides off the rail. Some have a separate lock lever for shift.
This is the front standard on all Sinar F, it is very basic and often used as an auxiliary / accessory standard support for adding bellows, lens shade and any other widget that is needed to aid in achieving the image goal.
Know these differences before considering any Sinar camera purchase. Sinar has their user manual on line:

Sinar Catalog noting their system offering. Know what is listed in this catalog is backwards compatible with Sinar Norma. With Sinar it is getting involved with a modular view camera system with near complete interchangeability-modularity allowing the modules to be configured as needed.

And yes, there are lots of Sinar cameras, camera outfits and accessories on the market at modest cost. Knowing these are the realities of the Sinar modular view camera system makes for many rational, logical and real world reasons to get involved with the Sinar system.
