There is basically one application for this: poetry, which would be too ugly with code block due to fixed width font:
Paragraph 1 Line 1\br
Paragraph 1 Line 2\br

Paragraph 2 Line 1\br
Paragraph 2 Line 2\br
which renders as:
Paragraph 1 Line 1
Paragraph 1 Line 2
Paragraph 2 Line 1
Paragraph 2 Line 2
