DBI states that DBD drivers should provide a Bundle::DBD::Foo to
leverage the CPAN 'Bundle' mechanism. (ref:

As a result many of the DBD driver distributions - such as DBD::Pg,
DBD::mysql, DBD::CSV - provide such a Bundle. Note that DBD::ODBC and
DBD::Oracle do not have a corresponding Bundle.
However the Bundle mechanism, which is described at
https://metacpan.org/module/CPAN#Bundles - is deprecated; dependencies
for DBD drivers can be correctly specified in Makefile.PL, Build.PL
and/or dist.ini
I brought this issue up on #dbi, was pointed to #toolchain , asked
there and they confirmed my assumption that the Bundle:: modules don't
serve any purpose; or at least not anymore, and probably for a *very*
long time already.
It could be that people 'depend' on a Bundle module so I think we
should not remove existing bundles.
my proposal is:
- Remove the section from DBI documentation that states a DBD should
have a Bundle
- Update the text in the existing Bundles, which now typically reads
someting along the lines of "This bundle includes all that is needed
to connect with a MySQL server using DBI." to "This file exists for
historical reasons."
Feedback very welcome!

I've never used bundles myself and certainly never produced one for DBD::ODBC.
I never liked the text "This bundle includes all that is needed to connect with a
MySQL server using DBI" since it is not true, you need a mysql client library too.
With dependencies in modules I don't see why they are necessary any more.
As such, your proposal sounds ok to me.
