Yes, in this case.  But there is no reliable standard just what
docstrip flag might get used for the driver file.

The above file also has

%    \begin{macrocode}
%<installer> \input docstrip
%<installer&make> \askforoverwritefalse
%<installer> \generate{
%<installer>    \file{suffix.drv}{\from{suffix.dtx}{driver}}
%<installer>    \file{bigfoot.drv}{\from{bigfoot.dtx}{driver}}
%<installer&!make>    \usedir{tex/latex/bigfoot}
%<installer>    \file{suffix.sty}{\from{suffix.dtx}{style}}
%<installer>    \file{bigfoot.sty}{\from{bigfoot.dtx}{style}}
%<installer> }
%<installer> \endbatchfile
%    \end{macrocode}

which is supposed to end up in xxx.ins.

I don't think that anybody can demand that.  Running LaTeX required a
working master file, and a working master file is either the file
itself, in which case it will sport an uncommented preamble, or a
separate driver file, which then needs to be the master file.

Anyway, it would appear that the info for bigfoot.drv is not
overwritten by that of bigfoot.dtx, but rather that for bigfoot.sty.
This is all a mess.  We really should not strip extensions when
parsing style info.
