If it is the consideration being given to an elderly queen that sticks in the throat, then perhaps it is time to consider two things.
The sovereign is the commander-in-chief of the armed forces, and as such it is her duty to be present and take the salute at the service of remembrance for those who died while serving under her. She would no doubt consider it a dereliction of that duty to leave early.
The older (and well venerated) veterans who find the long service in the cold a great strain would think it a disgrace to admit that the ceremony was too much for them, but their respect and chivalry toward their ageing female sovereign, who they swore to serve when they joined the armed forces, would allow them to accept a shortened ceremony out of concern for her.
So it was not just that pesky royal personage whose comfort (and pride) was considered. Not that it matters now, as it seems that it is back to the long-drawn-out status quo.
