Plugin index - entry not included in calibre list

One of the mods added my plugin to the index (post is here), but so far (it's over a week) it's not visible in the calibre plugins' list. I'm thinking, if it's something in my plugin's structure or something else.
On my side I was thinking, if version and plugin name in side file (consts.py, then imported to __init__.py and used in Source class) are making any problems for the Plugin updater to read required data and it skips it or is it something else.
