I can see your point but I think it falls into the 'solution looking for a problem' category particularly as, to take your case, who's to say that 21E won't get taken just after you've collected your new boarding pass (by a stand-by, a late connection, or someone being moved for 'I need to sit next to my child in 21F' reasons?)
Well,ofcourse there are no guarantees that the seat next to you will be free,but this strategy has worked very well for me in the last few years.

Normally (at least on RJ),the flight has closed for check in at this time (5-10 min till boarding) and all stand by is cleared...and in LHR T5...would not the conformance requirement make this impossible? I am not sure,but I presume so.Possibly on some airlines it may be diffirent ofcourse.
It would not solve the "I need to sit next to my child in 21F'",although on CX the crew's manifest shows the blocked seats and they do ask people not to sit there.
