I use other tools (excel, etc) to manage my people in the database. It would be fantastic if there was a hyperlink format that would open RM (and appropriate rmtree file) and bring me right to my person.
Example: rootsmagic://person/123
When clicked, RM opens (or comes to front window if open) and brings me right to person with ID “123”.
I assume this is not possible now, but would love to be proven wrong! 
LMK if this should be a support / feature request.
You can create hyperlinks in Excel (or PDF) then link to MyRootMagic Tree (or Gedsite etc or other sites.)
But it sounds link you want to bring up an Edit screen from a Hyperlink. I suspect the reason for hesitation from RM POV would be supporting that might be challenging.

Correct - I do NOT want to go to a website (like MyRootsMagic Tree). The behavior is similar in how Slack and other native application can open from a URL with a special protocol prefix.
that is what I thought – I am not a developer but I suspect that is much more complicated to support than it might sound.

What is the use case you have in mind?.
At this point, RM does not even open a .rmtree file from the OS file manager. Many would be happy to have that enhancement. Even the opening of the app itself is fairly heavy going let alone also opening a database file and populating the screen with data.
