I am really excited for the next year 2022. I think it is going to be best year of WordPress. Tons of new opportunities will be created as Major breaking changes take place. Obviously, if you want to stay outdated then it is another thing. Looking forward to :
a. Removal of Theme Customizer
b. Remove of WordPress Menus
c. Gutenberg first Templates.
d. No Themes. Let “Themes be Themes” philosophy of WP is amazing.
e. No Page builders, Gutenberg will rock.
f. Removal of Classic editor.
g. No metaboxes ? ( not sure )
