Thanks for the clarification. I’ll try to figure out something.
So far I have 3 licenses. One I used to use for building websites for my clients on my development server and it was never used for any staged site. The 2nd I use for my own website (production + staging) and the 3rd is actually not in use right now. Luckily every client of mine did purchase an own license once the project went life - around 20 projects so far. Still I often keep the production state at my server for maintenance purpose… testing updates and/or developing new functions / pages before they go live. Here I will ask my clients to put my development server as their production license. That may help.
Some time ago (in 2018 I think) someone in the forum asked about a developer license of X or Pro and you guys said it’s not possible because the theme is sold via envato. Now, that you sell the theme by yourself, may it be an option to consider?
Looking forward to the new products and services you’re going to roll out… also about editing archive templates etc somewhere in the future (I’ve read it in a comment of one of your staff)… I had to use Elementor for a project recently because of not being able to customize simple product, archive, category templates for a woocommerce website just by using Pro… tbh… I felt very restricted by the options (breakpoints, page JS etc) Elementor offers 
Best regards and stay healthy.
