Stricter docs for WP_Query::is_page()

[SergeyBiryukov]

Just noting the same should also be done for these functions:

• is_post_type_archive()
• is_attachment()
• is_author()
• is_category()
• is_tag()
• is_tax()
• is_single()
• is_singular()

and their WP_Query counterpart methods.

With 5.4 Beta 1 approaching and this ticket needing more work, this is being moved to Future Release. If any maintainer or committer feels this can be resolved in time, or wishes to assume ownership during a specific cycle, feel free to update the milestone.

Replying to SergeyBiryukov:

Just noting the same should also be done for these functions

is_author(), is_category(), is_tag(), is_tax() were addressed in [47397].

In 47401:

Docs: Synchronize parameter descriptions for conditional tags with their WP_Query counterpart methods.

See #48354, #48303.
