Responsive [navbar,] not visible without viewport meta tag

[westurner]

In layout.html, there's this:

{%- if theme_noresponsive|tobool and theme_bootstrap_version == "3" %}
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
{%- endif %}

I can only see the responsive top navigation menu (with the Chrome DevTools responsive tester) when I change it to this:

{%- if not (theme_noresponsive|tobool) and theme_bootstrap_version == "3" %}
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
{%- endif %}

# or this
{%- if theme_bootstrap_version == "3" %}
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
{%- endif %}

But is there any reason not to just always include the viewport meta tag?

    <meta name="viewport" content="width=device-width, initial-scale=1.0">
