There are exceptions.There a couple of ways to achieve such alignment, since both *roff and Texinfo fill lines by default and are therefore flexible with respect to input line endings. In *roff, of course, you _have_ to break an input line to make a macro call, and in Texinfo you don't. Let me take an example at random from bashref.texi and bash.1.

In *roff, you can write that either with escape sequences or a macro call: B> The return status is the exit status of the last command that executes.

Since I maintain six separate documents, the style I choose usually
depends on the style for the document where a particular piece of text
originates. I put two documents into two separate windows in my
editor and view them together. Most of the time, that's the texinfo
style, or the troff inline format change style, since it's most flexible.
For an example of this flexibility, even the .BI macro can't reproduce
the existing formatting of an array assignment without some more inline
formatting changes:
\fBdeclare \-a\fP \fIname\fP[\fIsubscript\fP]
I guess I don't see that stuff as broken or needing to be changed,
since the output renders the way I want. (Yes, I realize that the
texinfo output isn't quite like that, either. There's a limit to
how much fiddling I want to do.)
Is there any benefit besides getting the italic corrections groff
gives you?
