ProFTPD, 1.3.6, and certificates

[Ben RUBSON]

Hello,

I widely use ProFTPD with TLS module and password-protected SSL certificates.
I do not store the passphrase anywhere on the server but, for security  
reasons, enter it manually at server startup.
With Debian 9 and systemd, I had to use the following trick into ProFTPD  
configuration to achieve this :
TLSPassPhraseProvider /bin/systemd-ask-password
Would be nice I think to at least add it as a comment into tls.conf.

Then, what about ProFTPD 1.3.6 ? Do you plan to provide it ?
Would really be nice to have it in Debian Buster.
It especially include the following bug correction :
http://bugs.proftpd.org/show_bug.cgi?id=4260
which would really help with the configuration above.

Thank you very much !

Best regards,

Ben
