Limit of 5 domain names per certificate - any plan to increase it?


I wanted to try replacing Let's Encrypt with Buypass, since support for Legacy systems is important to me, and your CA is trusted since 2010-10-26, unlike Let's Encrypt whose new CA is only trusted since 2015-06-04.

I've seen that trying to issue a certificate for more than 5 Subject Alternate Names fails with error `MALFORMED_BAD_REQUEST` and detail `Certificate won't be issued for more than 5 domain(s)`.

Do you plan to increase this limit in the future? Let's Encrypt currently has a limit of 100.

Thank you very much in advance!

Best regards,
