Is pdf for mat dropped?

Hi everybody!

First of all thanks for all the work you guys are doing for mat. Over time it has become one of my standard installs. Having said that, I have a questions about the latest version. We're in the process of upgrading our boxen from *buntu 16.04 LTS to 18.04 LTS. And as such, mat is (re)installed, together with its dependencies (python-mutagen python-pdfrw libimage-exiftool-perl gir1.2-poppler-0.18) Today, one of our users mentioned that the mat version on his newly installed system did not support PFDs any more. Checking, mat does indeed give a File format not supported.

Curious, I compared the mat install on a 16.04 (which works absolutely fine) with a 18.04 install and saw:

Since the only difference I can spot is the difference in mat version numbers (i.e. 0.6.1-2 vs 0.6.1-4) and the fact that pdf is no longer listed under mat -l I just wanted to make sure: Is support for pdf dropped in mat version 0.6.1-4, or should I be looking at a different cause for this?

Thanks in advance!
