[Feature Request]: Memory Purging Features Backported to 1.16.5

[wuvvie]

Mod

FTB Chunks (1605.3.4-build.220 - 1.16.5)

Description

There is no memory management config available for the 1.16.5 version of FTB Chunks (1605.3.4). This version is incredibly taxing on system memory with how map data is held onto.
Specifically this is an issue in multiplayer servers with lots of claims. Having FTB Chunks on the client results in unplayable garbage collection stuttering, even using g1gc + several other args.

Describe the solution you'd like

Memory management features backported to 1.16.5 from more recent versions:
autorelease_on_map_close, max_zoom_constraint, and region_release_time would be fantastic to have in config and would likely solve the issue.
Ideally released on CurseForge so I can include the update in my pack.

If you don't support this version any longer, can I change your mind via offer of my firstborn and/or a sum of money through a third party payment service for your time 👉 👈

Describe alternatives you've considered

I am using a modpack with 200 mods, including Journeymap. I considered if JM was the problem (since my logs would show errors with Journeymap before I ran out of memory) and have thoroughly troubleshooted this avenue with the dev, and it is not the issue. Even with JM removed, the memory leak from FTB Chunks results in constant garbage collection stuttering.
I have optimized the available configs but I am not able to get performance better than ~10 seconds between garbage collection stutters. Removing FTBChunks fixes all memory issues.
