I've asked this question here whether it was possible to implement MARS gates in MSFS 2020. Boris said here that it is not possible to do this in MSFS at the moment. I'm suggesting to support/implement this system officially as:
- There is a case study on this system: https://pdf4pro.com/view/for-many-airports-mars-is-closer-than-ever-5a46e9.html
- A published research paper for this topic: https://www.sciencedirect.com/science/article/abs/pii/S037722172101033X
- ICAO Apron Management and Safety Advisory Document outlines the importance and usage of MARS as well: https://www.icao.int/MID/MIDANPIRG/Documents/MID19%20and%20RASGMID9/RSA-15-%20Apron%20Management.pdf
This system has been implemented/being implemented in lots of airports all around the world as it increases capacity (almost doubles it) and efficiency.
Sao Paulo Guarulhos Airport
London Heathrow Airport
San Francisco Airport

In my question post, @Boris_ mentioned the parking radius and services. For MARS gates, the lines clearly mark the aircraft movement area and ground services. The ground services never wait on the side, or if they will, they do it in a way so that the other gate would not be blocked, for example:
Suggestion is to add a way to implement this system so that MARS gates and jetways can be used and simulated in the simulator as lots of big airports in the world use this system extensively.
