I had not realised the extent and significanceof the way that this issue extends beyond T builds (or is a different issue which coincided.)
For instance a user wanting to install lemonade does see the "new type bundled recovery .zip file"
Where “Recovery and boot img” is IMG-e-1.15-s-20230916331435-dev-lemonade.zip
While a new user wanting to install renoir at Android 12 (S) does not know why the install instructions, mentioning “the contents of the eRecovery zip file” do not fit the published files.
I know you made an apology about the timing, my comment is only that I did not realise that the new packaging method appears to extend to other Android versions beyond T. (Unless I am wrong again !)
This would seem a great improvement from what I see of the extracted lemonade Android 12 (S) file 
My actual point in writing was to suggest that the method to extract images with a payload dumper, should perhaps be under a heading carrying the meaning “delayed publication of bundled recovery files” rather than the heading T builds.
