Hi Tom (Gibson):
IIUC, you allude to the issues addressed in this thread:
https://www.fsdeveloper.com/forum/threads/ade-extra-objects.432461/
I am familiar with that discussion and all the whys and wherefores it involves.
Additionally I am aware of options for liberating objects that may have been "geolocked" inside certain XML element contexts:
https://www.fsdeveloper.com/forum/resources/geolock.274/
https://www.fsdeveloper.com/forum/threads/geolock-beta-thread.437490/
And you may recall your assertions in these post to other threads ...here:

My assumption is that Tomt478 is referring to MDLs that he has the right to use and/or has created entirely on his own.
Working within that assumption, I cite a workflow that imports from BGLs and results in a source folder of loose MDLs.
That workflow utilized scruffyduck's Library Object Manager (LOM) <I should have specified that instead of 'ADE' -sorry>.
https://library.avsim.net/file/81175-library-object-manager
One subsequently had the option to use scruffyduck's LOM2ADE utility to import loose MDLs from LOM
into ADE's LOM.

It is of course, possible for ADE to create a database of Scenery Library Object MDL source BGL files from which to place objects.
However, AFAIK, Tomt478 "would" IMHO, likely plan on using imported loose MDLs into ADE in order to use ADE for placement.
If he wanted to keep MDLs in existing Scenery Library Object BGLs, he would
not be able to re-organize them as he intended.
Alternatively, he can just use the original scruffyduck Library Object Manager (LOM) as a stand-alone utility to re-organize MDLs.
That same utility can be used for placement, IIRC.
Then, if Tomt478 wishes, he can import re-organized Scenery Library Object BGLs into ADE as indexed source files.
Or he can then use scruffyduck's LOM2ADE utility to import Scenery Library Object BGLs as loose MDLs from LOM into ADE.
Alternatively, he can use MCX Object Placement feature to manage / process BGLs and MDLs, then "place" them as well.
Ideally, Tomt478 would instead purchase- and use- Instant Scenery 3 via Flight1 (it is still sold by them- but not supported)
