@dinakozlov

can we request the longer chain?

Continuing the discussion from Shortening the Let's Encrypt Chain of Trust:

@aarongable

The summary is:

• On 2024-02-08, we will stop providing the long chain by default, but clients can still be configured to request it.
• On 2024-06-06, we will stop providing the long chain at all.
• On 2024-09-30, the cross-sign will expire, and any websites still serving it in their TLS handshakes may run into difficulties.
