For context, it was decided to remove and deprecate the Compatible Token contracts LSP7CompatibleERC20 and LSP8CompatibleERC721 for the following reasons:

• Compatible token contracts are problematic as they bind 2 specifications (LSP7 + ERC20, LSP8 + ERC721) that can sometimes be opposite to each other.

• High gas cost for transactions: because of the multiple storage writes (on ERC721 for operators approval for all), notifications hooks (onERC721Received + LSP1 hooks) and events emitted from both standards (e.g: Transfer from LSP7 + ERC20), this creates a very high gas cost for any transfer or operator approval transaction. The highest being safeTransferFrom from LSP8CompatibleERC721 which incurs all of these points defined previously.

• These contracts go against the vision of LUKSO to encourage LSP7 + LSP8 standards on the LUKSO blockchain, compared to use these old ERC20 + ERC721 standards that carry issues and limitations that we hope being addressed by both LSP7 + LSP8

• security reasons: it is very easy for a developer to just assume the compatible extensions work exactly like the ERC20 and ERC721 they are familiar with, which could create security problems (eg. not caring about the universal receiver callback).

Therefore, deprecating them feels like a good idea, the compatible extensions feel like forcing LSP7 and LSP8 to do things that they weren't meant to do in the first place.
