Preconditions and environment

• Magento version 2.4.8

Could you explain the rationale behind having the EmailMessage class extend the Message class, rather than a class directly related to email sending, such as Mail? Additionally, since the Message class does not provide methods like attach to handle attachments, how does Magento handle email attachments in this architecture?

Steps to reproduce

Create a script for send email
use method "attach" to add attachment

Expected result

It is not possible to add an attachment.

Actual result

It is not possible to add an attachment.
