[COT] Propose ways for plugins and extensions to declare compatibility with custom order tables.

[vedanshujain]

When we rollout, all plugins and extensions will not be compatible with custom order tables, and we should display this to the merchant if they enable COT for a painless experience.

This could be a filter that extensions can use to declare compatibility, or this could be a plugin header field. Note that we may eventually roll our custom tables for products, customers and other entities, so ideally solution here should be extensible to these future enhancements as well.

We should also look into ways for plugins to find out whether a feature is implemented or not, and then plugins should have ways to declare support for particular feature.

For this you could implement something like wc_add_support() and wc_get_support(), modeled after add_theme_support() and get_theme_support().

Such as: wc_add_support( 'custom-order-tables', ...$args );

Just a thought.

@Konamiman This one could be closed?

This one could be closed?

Yes, as we implemented the features engine already.

@Konamiman @rrennick Hi, Just wondering what the solution is here. It's mentioned that the feature has been implemented, but no mention of how plugin developers should actually declare compatibility.

@maddisondesigns You can find that at https://github.com/woocommerce/woocommerce/wiki/High-Performance-Order-Storage-Upgrade-Recipe-Book#declaring-extension-incompatibility.
