IIRC this was what you already advertised on your first round of
DBD::File internals redesign.
As long as "users" of DBD::File are not harmed, go ahead.
I do not want a truckload of code like
http://repo.or.cz/w/DBD-CSV.git/blob/8d7f4284:/lib/DBD/CSV.pm#l90
which has now been removed as the prereq's are higher:
PREREQ_PM => {
"DBI" => 1.614,
"DBD::File" => 0.40,
"Text::CSV_XS" => 0.91,
"SQL::Statement" => 1.33,
"Test::More" => 0.90,
"Encode" => 0,
"charnames" => 0,
},
But in future upgrades/updates, code like that is not unlikely to
re-appear
