(OP)
Some screen printers has the complex squeegee drop/lift mechanism with squeegee down stop parameter and separate unit for squeegee pressure. Is there any disadvantage if this mechanism is replaced by a simple pneumatic drop mechanism mainly consist of one cylinder and a pressure regulator?

The lifting of the screen frame DURING the print stroke is called "peel" and must be adjusted to match the SPEED & STROKE of the PRINT squeegee.
The up/down and front/back travel of the "flood" and "print" squeegees is also usually regulated in terms of speed & travel distance. Some "high end" presses use several cylinders across the print squeegee to maintain uniform pressure.
Some simple presses may be able to combine print & flood motions with the same cylinder, but these will cause big problems with more precise work. Ask me how I know!
The answer to your question depends on the type of printing the press will need to do.
