Emacs currently has more than 9K user options. We should only add new

"separating tabs".
Also, please leave two SPC characters between sentences.

Well maybe because packages which have separator allows to customize
them (e.g which-key-separator, imenu-level-separator,
uniquify-separator), but I've noticed that most packages doesn't allow
changing the separator or are as plain variables
(e.g. menu-bar-separator, eldoc-doc-buffer-separator), i don't know if
this is a kind of coding convention, but if so then i'm closing this
bug.

Well maybe because packages which have separator allows to customize
them (e.g which-key-separator, imenu-level-separator,
uniquify-separator), but I've noticed that most packages doesn't allow
changing the separator or are as plain variables
(e.g. menu-bar-separator, eldoc-doc-buffer-separator), i don't know if
this is a kind of coding convention, but if so then i'm closing this
bug.

Most likely when users might want to change 'tab-line-separator'
they will also want to apply text properties to it as well.
But the Customization UI doesn't support editing text properties.
This explains why, for example, 'eldoc-doc-buffer-separator' whose
default value contains text properties is not defcustom:
(defvar eldoc-doc-buffer-separator
(concat "\n" (propertize "\n" 'face '(:inherit separator-line :extend t)) "\n")
"String used to separate items in Eldoc documentation buffer.")

I just cannot imagine a reason to customize just the separator of the
tab-line.
