Absolutely. There is (usually) quite a high level of discussion on these forums. Adding grunts and sighs will not improve the conversation, may make it worse. Simplicity is beautiful.
The Solved marker might be useful, but as @MSmithy points out, PhotoLab is an artist’s tool, and there’s often more than one solution to most problems, some better, some worse. An early solved might kill useful discussion. Most of us would check the solution anyway and chime in. I would hate though to see this forum go in the StackOverflow (same creators as Discourse, Jeff Atwood) direction, with points and comments on comments though.
What I would like back are higher quality and larger images again. These are important for the integrity of the work and demos. My own images were massacred on a how-to thread, forcing me to create a zip file and upload it to Proton Drive and link it here, if I want other photographers to see what I saw when creating the tutorial examples. This does not mean that the forum has to leave jpegs at full size. I use ImageOptim before uploading my images, which is an almost lossless way to shed about 80% of the bulk of an image, but it looks the same to the human eye. The forum could run a similar routine with uploaded images to save both disk space and bandwidth.
