This is almost always a good thing.
There are of course centralizations and standardizations - the AWS SDK, Console UX, API guarantees, etc.
But Honeycode has almost no relationship to the rest of AWS, technically, or organizationally.
The last time I dealt with AWS and amplify, this was glaringly obvious in several places. Settings pages where one tab looked and behaved radically different from the other. A seeming total lack of communication between teams resulting in badly synced package released with bugs due to version differences. Also frequent omissions in documentation requiring you to hunt it down in github repos or in totally different places(Say Amplify uses X to do something, you might have to find info for using X in an Amplify context in the X docs).
2. Once you have more than 3,000 or so rows in a workbook, everything grinds to a crawl. It can literally take over a minute for any kind of data mutation in the administration user interface or in the app interface to be reflected in the display. This means that doing anything on the app becomes literally slower than if you were to do it with paper and pencil. And this is despite paying $20/month for the Plus tier, which purportedly allows 10,000 rows per workbook.
3. The project lacks polish and user-friendliness throughout.
4. It is buggy throughout, and developer updates have introduced new bugs multiple times. For example, recently the last record in a table started getting displayed in my app view even though it is excluded by the list filter in that view.
5. The bug reporting process is difficult to the point that I don't even bother anymore.
6. The first time you try to open an old workbook, it will error out. Presumably they are using serverless and the Lambda function is cold.
