Well... I have some technical and some non-technical responses to
this.

Technical 1.
Your macro is not equivalent to the vi :g/<pat>/d unless it is
embedded into a loop.  The loop could be programmatic or interactive
(keep doing Cx e)

Technical 2.
Overall it turns out faster (without the infrequently used flush-
lines) to
Save-buffer in emacs
Finish off the 1 liner in vi
revert-buffer in emacs

Non-technical 1
I work in an environment where I am the old-timer using the strange
old clunky emacs. I have a hell of a time convincing my half-my-age
coworkers to use emacs.  Confirming the clunkyness (because I dont
know a command) does not help my cause :-)

Non-technical 2
Funnily enough, this requirement came up in a large scale edit that
required adding a single line to 200 classes in 37 files.  I did this
(for these coworkers) by writing 3 elisp functions that implemented an
iterator that sequentially went through the 200 classes.  Producing
the file:lineNo list of those 200 cases was where the original request
(for deleting lines) came up.

So, no, Im not averse to writing emacs macros or elisp code; just like
to use the right tool for the job.
