Yes, I understood that, what I meant was whether there will be some
if-else sections that treat either the old format in pma_column_info
( x_y__t.inc.php ), either the new one ( x_y_t.class.php )?
And if so, this leads to the next question.

(I am sorry again for the misunderstanding) I meant if the user
has a table that contains old transformations on columns, and
he tries to modify that, what happens? If he has transformation 1
(x_y__transf1.inc.php) and wants to switch to transformation 2,
will that become x_y__transf2.inc.php or transf2-neutral-string
in his pma_column_info table?
To summarize, if we choose the permanent code version, will
that imply treating both cases and leaving the pma_column_info
unchanged for the users that have the old format? Otherwise,
they will have a mixture of old and new transformation entries.
The only way I see to change them all without a script, would
be to run a full update (for all of the entries) on their column_info
table every time (hopefully only the first) an old format
transformation is found and replace it with the new neutral string.
