New description:

 During #23577, we discovered that there's a lot of code in
 setup_introduce1_data() that's duplicated in service_intro_point_new() and
 hs_desc_lspec_to_trunnel().

 In #23576, we removed the duplication across setup_introduce1_data() and
 service_intro_point_new(), creating node_get_link_specifier_smartlist().

 So we should clean that up at some point, but it's complicated, because
 the intro point functions use hs_desc_link_specifier_t. (See #22781)

 Edit: update after #23576.

Comment:

 Oops, no we don't.

 Fixing #23576 removes the duplication across setup_introduce1_data() and
 service_intro_point_new().
