It does get plenty of love. It's just that out of all the Infinity Engine games, it has the most changes and lynxlynxlynx is developing GemRB almost on his own for the past five years. The engine was already outdated at that point, so they added in graphical changes and switched to the 3rd edition of Dungeons & Dragons, so it takes more love to support than the other games (save for Planescape: Torment maybe, which was forked before Baldur's Gate was even released).
