Hi Lynn,

> There are automated data exports with prices, that will be automatically
consumed on the other side.

I agree that these cases can go horribly wrong. However, my reasoning is
the following:
- if a piece of code currently relies on locale-independence (e.g.
automated data exports) then this
change wouldn't cause any breakage since a workaround has already been in
place there (e.g. the
programmers use var_export() instead of casting)
- if a piece of code relies on the locale-dependent string representation
of floats then there will be
a BC break, sure, however I believe that code isn't very sensitive to the
change in the vast majority of the
cases since that data is for presentation purposes only.

Or do you have other locale-dependent use-cases in mind? I am sure there
are some but I think the number of the situations where the change is
problematic is less than what it first seems.

Regards,
Máté
