Business-oriented releases like this need to come with a guarantee of existence for X years (some reasonable number) if Google expects anyone to use this for business purposes -- especially any paid/G-suite version (or whatever their premium version is called this week). Even then, it'd be a tough sell, as simply not shutting off the servers doesn't mean they'll actually actively update and support it.
Google, an advertising company, is competing against Microsoft, a software company with its roots in this exact type of software and thousand of companies with piles of MS-specific macros and scripts and processes they've been working with since the 90s.
Half-assing it is not going to work, even if they have a free tier available.
I use Google Drive regularly for personal documents, and even for my one-person business, but I wouldn't dream of entrenching myself in it in such a way that operations could be disrupted if they decide to switch the servers off next week with two days warning.
Search isn't going away. Maps isn't going away. But everything else Google is subject to a shut off at any second. Gmail isn't going away either, but your specific account could, with no recourse or appeal or access to your data.
The question we should all be asking at the release of ANY new Google feature shouldn't be "does Google have the engineering talent to make this good?". Of course they do. If Google wanted to start making space rockets tomorrow they could. The right question is "does Google have incentive in the form of advertising revenue to keep working on this?"
I predict this is another feature that has already been abandoned as of this writing, with no further updates to come.
