Firstly, thanks for your feedback. I really got your point.
Like every field in tech, using this tool has some trade-offs, like you said tests may not be permanent and require hand-written tests. Yet, creating them is easier when you compare with writing tests with coding/hand. Also, this tool can be used as a helper. For instance, getting unique selectors, or creating a test with this tool and then modifying it by hand could be really useful, too.
As a conclusion, according to my developing this kind of tools can really improve and ease the test phase, and can encourage developers to create more tests.
