9D This is such a superb &lit anagram clue which did not get proper credit from the blogger

15D The ? at the end should be enough to answer Gaufrid’s misgiving about what exactly was being delivered.

I felt that overall, this is one of Jason’s better efforts, inadequately reflected in Gaufrid’s comments.

Apologies, Gaufrid, I worded my comment badly. ‘Peahen’ and ‘hen’ are too closely associated: a peahen could, itself, be ‘a broody sitter’.

I originally typed THES[pian] but then decided that ‘short’ to indicate ‘half of’ didn’t really work so as Chambers only has ‘thesp’ it in its own right, and not as an abbreviation (Collins and COED do not list it as an abbreviation either), I decided that it fitted the clue better.

For the anagram indicator in 10ac I went down the path easily-yieldingly-compliantly-flexibly which seemed to work, at least for me.

I take your point about things being able to have a space between them but can still considered to be beside each other. I was being too analytical because I would have said that the full stop was beside the last letter of the sentence.

I can’t really add anything to your musings on your problems but, considering the weakness of some of the other clues, I think there’s probably not much more to find. A ‘thesp’ is already ‘a short actor’, being an abbreviation of thespian [I see Chambers - alone - gives it as a word in its own right] so ‘thes’ is a very short actor!

In 20dn, I thought using ‘a hen’ to clue ‘peahen’ was very poor.

And ‘easily to’ as an anagram indicator?

Re 4dn: I did take ‘the point’ as meaning ‘full stop’ and don’t see any problem with there being a space. There usually is a space between two things that are beside each other!

Re 15dn, I don’t know, nor can find, any such expression, so I think ‘greens’ must have been chosen, as having a range of meanings, in order to mislead.

In spite of the reservations mentioned, I did like 9dn.
