Much like Vercel, A Record supports would be a huge benefit to Railway.

CNAME flattening isn't widely supported and the recommendation is to move to Cloudflare. As an Agency however, it isn't always feasible to do this, for a few reasons.

1. Clients can often have complex DNS setups to allow for their various systems which we wouldn't necessarily support outside of the website. Suggesting a change in DNS provider can be a huge undertaking for some companies in which using Railway would not be enough to convince them over alternative providers.

2. Clients may not have in house IT expertise in which we assist in updating the DNS records, changing over the DNS provider will transfer the accountability for the entire DNS over to us, often, including MX records or any domain verification they may need in the future.

3. Government funded websites such as local councils are often locked to providers and changing the DNS provider will not be possible.

At the moment, as an Agency, this is a blocker to utilising Railway completely and for us is preventing us seeing Railway as a legitimate alternative to Vercel for frontend hosting.
