Don't you think that the Seo4SMF should focus only on stability... and as new features for seo are introduced, re-focus on stability ?
Possibiliy adding optimizations to SEO .htaccess ...
# cache images and flash content for one month
<FilesMatch ".(flv|gif|jpg|jpeg|png|ico|swf)$">
Header set Cache-Control "max-age=2592000"
</FilesMatch>
# cache text, css, and javascript files for one week
<FilesMatch ".(js|css|pdf|txt)$">
Header set Cache-Control "max-age=604800"
</FilesMatch>
# cache html and htm files for one day
<FilesMatch ".(html|htm)$">
Header set Cache-Control "max-age=43200"
</FilesMatch>
# explicitly disable caching for scripts and other dynamic files
<FilesMatch "\.(pl|php|cgi|spl|scgi|fcgi)$">
Header unset Cache-Control
</FilesMatch>
# Prevent .htaccess and .htpasswd files from being viewed by web clients

I think the social booking mod and everything else should be developed separately from the SEO mod. Fewer variables (unrelated to SEO) to focus on = less chance of something else interferring with SEO mod.
