You could apply a table, table-cell fallback for non-supported browsers

[dagda1]

Currently there is no fallback for browsers that do not support flexbox for equal.

You could make .equal this:

.gel-layout--equal {
  display: table;
  table-layout: fixed;
  width: 100%;
  display: flex;
}

.gel-layout--equal > .gel-layout__item {
    display: table-cell;
    display: -webkit-flex;
    display: flex;
} 

Would you be open to a PR that did this?
