Let me ask one question first, in order to avoid miscommunication,
as I really want to get the first step for v2.0-rc4 in a concrete
shape tomorrow.  Do you think gradual transition worth pursuing or
do you think it is a waste of time?

I do not think it matters that much, but since you said you do not

What I meant was that when they update their Git (perhaps at the
beginning of the week), the won't know they will now be running
stale code.  The warning comes only when they first run it (perhaps
at the end of the week) to do some real work with a remote hg
repository, which may not be a convenient time to do their sysadmin
task.  And the next time when they update their Git, they may have
already forgotten about the warning.  The ideal transition would be
to somehow let them notice when they are in sysadmin mode.

Renaming the directory will not "break at the build time" for those
who have already did "ln -s" these scripts, of course, but it will
"break at the build time" for others (i.e. those who "cp"), no?
Again, not very important, as I too consider it optional.  If you
are shooting for an expedited transition, it is perfectly fine to
drop it.

Perfect.  I did check the page when double-checking the URL while
writing the README thing, and I did skim the page, but I must have
missed it.

We could add these two to the warning, then, to discourage people
who see "please visit this URL" and say "Yuck, I have no time for
that" without actually visiting.

I think explained why the step 3 would not help very much compared
to the "there is no script, only README remains" endgame (and that
is why it is marked as "optional").  Actually, you reminded me that
a very short and easy-to-follow instruction is on the page referred
to from README and the warnings, which means that this step would
make even less difference compared to the endgame.

I don't think I saw you explain why that is not the case and why we
do want this step (and I cannot quite tell if you are aiming for
more gradual transition that wants this step, or an expedited one
that does not).  I am fine with either way.

In any case, I'd ask another question to avoid wasting time on
miscommunication.  By "This is what I want", do you mean you want
this step 3 also in v2.0, or do you mean you want 2 alone in v2.0
then step 3 some time later?

Unless you want 2 and 3 together at v2.0, we do not have to decide
the merit of step 3 before v2.0-rc4; if you do want 2 and 3 together
for v2.0, then your prompt answer matters a lot.

You said your "wish" wasn't "respected" in another message, when I
explained that I thought you did not want to disrupt v2.0 by
insisting on removing these scripts and that was why I listed
options that did not involve removal of the scripts.  Are you saying
that you wish you want to see them removed or crippled at v2.0?
Changing your mind after discussion is perfectly fine, by the way.
