The tag is present in Lintian version 2.104.318. That is the most recent version we know about.
For historical reasons, use of
cyrillic subdirectories of
/usr/share/fonts/X11 are permitted, but installation of files
into these directories is discouraged. Support for the first three font
types is deprecated or no longer available, and Cyrillic fonts should use
the normal font directories where possible.
Please refer to Debian Policy Manual section 11.8.5 for details.
