Personally I've come to appreciate that many closing tags are unnecessary in HTML. Makes many constructs much more concise. Especially with tables:
<table>
<caption>Some letters and numbers
<thead> <tr> <th>Letters <th>Numbers
<tbody>
<tr> <td>A <td>1
<tr> <td>B <td>2
<tr> <td>C <td>3
</table>I used to be team semi-colon in JS but I've switched teams now and have my formatter strip them. There's like 1 or 2 edge cases where that can bite you but practically speaking it's a non-issue. The real downside is that I sometimes get lazy when writing C++ and that very much dislikes poor punctuation.
