I use indented text as the best available mode for editing the
models.wrm file of ACeDB, if that means anything to the gentle reader.

Imagine I've just typed

?Method Function ?Text  // what does it do?
        Variant_of UNIQUE ?Method XREF Variant
        Variant ?Method
        Version Text
        Parameters Float_Params UNIQUE Text Float REPEAT 
                   Int_Params UNIQUE Text Int REPEAT
                   Text_Params UNIQUE Text Text REPEAT

and the next thing I want to type is

        Min_score UNIQUE  Float   // used in plotting

but indented-text-mode can't see that `directly under Parameters' is a
good place to stop.  So I end up moving up, typing the line, yanking it,
coming back down and inserting it where it belongs.  What I really want
is a command

> retract-tab-relative-to-prior-line	M-C-i
>
> Identify the lowest line above current in which there is a visible
> character to the left of (the vertical line through) point.  Identify
> the right-most visible character to the left of point, in that line,
> which is preceded by a hspace character.  In the current line, delete
> hspace characters to the left of point until either point is under the
> visible character identified or the character to the left of point is
> visible.

or something along those lines.  What are my chances of seeing such a
command in a later version of emacs ?  (Assuming I don't find the time
to write it myself ...)
