Is this now waiting on anything specifically?

Only T402810: Exploratory testing on PHP 8.3 for Content Transform Team components is open in the tree, but WMF prod is seemingly pretty stable on PHP 8.3, so from that point of view, probably unecessary to do much more there...

PHP 8.2 itself gets security support until 31 Dec 2026. I am not sure what the usual procedure is, but we might want to wait until we are closer to the end of this year and maybe drop it as part of 1.47?

edit: ignore, see below
