I also find it strange that there is no Gimp procedure equivalent to the remove alpha menu entry.
Only flatten the image and there IM is a winner.

Ask the Gimp developers about that one.  https://gitlab.gnome.org/GNOME/gimp/issues/

There are many GUI actions that do not have a direct API equivalent. In this particular case, there would be at least two ways to understand "remove alpha channel":

• merging in a default background (so the RGB content of transparent pixels is lost)
  

• setting A to 100%.
