I think that rule should be changed to ignore view files. It's mildly irritating to need to write e.g.

    <h1><?= $title ?></h1>
    <?= $stuff;

Or to edit a file like this:

    <h1><?= $title ?></h1>
    <?= $stuff; ?>
    <p>static!</p>

deleting the last line and that to cause a phpcs fail.
