Semi-intended. After a certain date in March, our maintainer preferred not to take anything more disruptive than documentation changes for the next release candidate (now out as RC4). (I understand that decision--bugs are never better at creeping in than when you are trying to stabilize a code base for release. "Just this one more fix!" draws software defects like cats to the sound of a tuna can opening.) I have a fix for the `bp` request on a Git branch.[1] I cannot say at this point whether it will get into groff 1.23.0 final--it's not solely my call. As I believe I noted previously, making `sp` "just work" the same way is tricky. I did add the following item to the NEWS file, quoted in the RC4 announcement email (admittedly, there's a _lot_ of news). ---snip--- o The s (ms) macro package now enables the formatter's "no-space mode" after ending displays (`DE`) and equations (`EQ`); this is to improve the fidelity of rendering of historical ms(7) documents such as Kernighan & Cherry's "Typesetting Mathematics". This change means that display distance spacing (the `DD` register) overrides paragraph spacing (the `PD` register) instead of accumulating with it. ---end snip--- If you can provide me with some concrete cases of your applications of `sp`, maybe I can better advise you.
