One might argue that forcing this change-of-style is a bit intrusive;
but on the other hand it's supported by debhelper in buster and
stretch-backports and is now the recommended way … So yes, I think a
migration would be a good idea.

I'm not sure if this works for each debhelper compatibility level;
reading the source at /usr/share/perl5/Debian/Debhelper/Dh_Lib.pm:

    # Lowest compat level supported
    'MIN_COMPAT_LEVEL' => 5,
    # Lowest compat level that does *not* cause deprecation
    # warnings
    'LOWEST_NON_DEPRECATED_COMPAT_LEVEL' => 9,
    # Lowest compat level to generate "debhelper-compat (= X)"
    # relations for.
    'LOWEST_VIRTUAL_DEBHELPER_COMPAT_LEVEL' => 9,
    # Highest compat level permitted
    'MAX_COMPAT_LEVEL' => 13,

suggest that we need at least compat level 9 for this.
(Interestingly, LOWEST_VIRTUAL_DEBHELPER_COMPAT_LEVEL doesn't seem to
be used anywhere …)


Cheers,
gregor
