Smart Objects being given 300MB extra weight

Question

Beginning in PS late 2022, I noticed that wrapping layers into Smart Objects would sometimes add 300MB to the file size, resulting in mammoth PSBs. The workaround I've found for this is as follows:

Open the Smart Object and check the PS Temporarary folder for the file size.

If it seems bloated, duplicate all layers to a New file and save it to desktop. (Note the smaller file size, if applicable.)

Use Replace Contents to link your top-level Smart Object to the new file.

If there is an easier way to do this, I am desperate to hear it. If there is not an update slated to fix this, there really should be!

Thanks.

On a bloated file, open main parent image, go to file > file info > raw data and check if there is a single line message stating that there is too much info to display.

Repeat this process for any smart objects and nested smart objects within smart objects.

If this is the case:
