Thank you for sharing your insights and valuable information. I appreciate the effort you put into your response. However, I sense a potential bias in your answer, particularly concerning the original question posed by the OP.
The OP was seeking advice on a smartphone without bloatware and with a high level of customizability, which I believe is the central focus of the discussion.
While I understand that security updates may be a concern for some users, it's worth noting that as of the October release notes (https://gitlab.e.foundation/e/os/releases/-/releases/v1.16-s), the integration of security fixes extends up to September.
Regarding support, I recommended the Murena phone, which comes with /e/OS out of the box and is based on the Fairphone + /e/OS combination. It's important to clarify that Murena is a commercial French company, meaning that support comes from them rather than directly from Fairphone. However, this arrangement offers the benefit of commercial protection, including a 2-year warranty. I also feel a little bit unfair the comment about support, as I think that installing GrapheneOS on any device will probably cut you from support from hardware and you will rely one GrapheneOS, that I'm sure has a very good support, but doesn't have any obligation to replace the device is a problem occur.
I also want to express my gratitude for the link you provided (https://divestos.org/misc/e.txt). Additionally, based on my personal experience, none of the mentioned bugs have affected me. This could be attributed to my use of the F-Droid store, allowing me to benefit from updates available there as well.
Once again, thank you for your input, and I hope this further clarifies the points discussed. I know that I have a specific usage of my phone, but I think the value of my proposal remains.
