This is a great opportunity for you! This is a problem you know lots of people have and since you are a technical user, you could probably solve this for yourself and others in the same situation. Write a small application and register a file extension for it (maybe .obsidian). When you double click on sql.obsidian (for example), your app would launch read that file then launch Obsidian via the obsidian:\\ protocol.

Your launcher app could also handle the creating of .obsidian files or (even better), write a plugin for obsidian to export a .obsidian file.
