Sorry, it is not clear why you need a new section type, it looks like you can always assign the symbol to an existing input or output section, no?

The general case you will have something like

foo_and_bar : {
  begin_foo = .; *(.foo*) end_foo = .;
  begin_bar = .; *(.bar*); end_bar = .;
 }

If there is any input section following a symbol, associate the symbol with the input section with an offset of 0.
If there is no input section following a symbol, associate the symbol with the end of the output section.
