Enable Bootstrap Layout Builder setup with Layout Builder Iframe Modal

Problem/Motivation

Composer installations of Bootstrap Layout Builder and Layout Builder Iframe Modal is impossible.

There is good cause to use Layout Builder Iframe for developers and users.
Bootstrap Layout Builder must be installed with the deprecated theme reset module, which is hard to uninstall once activated given the coded dependency of Bootstrap Layout Builder.
There is a general lack of coherency on front end modules versioning and dependency, making it impossible to use Drupal without falling back to recognized inferior unsupported techniques.

Steps to reproduce

Try to install Bootstrap layout builder with Iframe Modal and not the theme reset module.
There are further complications with block styles module.
All are tied in dependency. Can bootstrap Layout Builder work with Iframe Modal while theme reset is installed? Forum comments suggest a removal of theme reset before using Iframe modal. Its a hard situation for any designer developer.

Proposed resolution

The various module owners to implement the approved and preferred "Layout Builder Iframe Modal" with coherent associated dependencies especially with block styles and several other styling moodules. What are the correct ecosystems?
Iframe Modal Layout is intended for a dead module Layout Builder.
Please discuss and make sense of this space for the community, especially for new designers and developers.

Remaining tasks

Approval of Layout Builder Iframe Modal perhaps?
There seems to be consensus.
Implementation for composer installations to work.
