Hi Lynn,

Thank you very much for the input! Then we could add a secondary vote to
the RFC where an
upgrade path was decided upon.

The first such path is the one proposed by Christoph:
Introduce a temporary ini setting with which a "debug" mode of float to
string casting could be
enabled. That is, when it's turned on and a casting is affected by locale
settings then a warning
is emitted. This setting would be removed in a (near) future version of
PHP. Although
PHP 8.1 would be an unusual candidate to do so, but it *might* be possible
if we found a good
way to warn people from day 0 that it's just a temporary flag? Maybe by an
immediate deprecation?

Is there any other idea for a sensible upgrade path?
