What's the downside, if any, of using plugins that are not native requiring legacy support?

Is there a way to implement Community Builder with ALL native plugins for gallery, newsletter, PMS, forum and blog?

Thanks...

See this post: Difference between "1.5 Native" and "1.5 Legacy" .

First let me thank you for the quick reply and in general for what appears to be a tremendous (and probably thankless at times) job as moderator on the forum.

I have a problem however with your reply. Did you actually read the thread you directed me to after finding it in a search? I'm asking because it has nothing to do with my two-point question. It was primarily directed to developers who wanted to be "Native" and what constituted "Native".

I wanted to know what the downside was AND what plugins/addons/components/extensions that are Native and are recommended or are supported by CB.

I have already found the answer to the downside - slower performance in legacy mode.

Thanks again for your efforts.

I'm sorry you don't think my link applied. I thought it made some good points regarding legacy mode.

As far as what extensions are supported in CB, you can look in CB-Specific Joomla Extensions link in my signature. There won't be many claiming compatibility with 1.2 though till the release to make sure there will be no API changes. The good news is that most run anyway if you enable legacy, and legacy only affects those extensions that require it, meaning your Native extensions will not trigger the legacy mode.
