That's not upstream but it's more or less my point: Corporate users may
be stuck with older releases if they follow corporate practices like
using distribution rpm's and avoid building their own stuff.

There are ways around this like PPA/OBS/EPEL or using container setups.
The switch to PHP7 also means a considerable performance boost (even
without the free opcache extension)

These are the enterprise distributions mentioned above.

There is no SuSE 15.1

- There is OpenSUSE Leap=A0 with php 7.2, (15.2 is in early alpha)=A0

- OpenSUSE Tumbleweed with php 7.3.11

- SUSE Linux Enterprise Server (SLES) has abandoned PHP from the core
release. All recent SLES 15 SPx have a common "Web and Scripting Module"
which contains PHP, Python3 and other goodies.
This module is no longer bound to the long-living BC and ABI promises
and they can bump versions anytime they (SUSE) find it apropriate. They
also used to ship two different sets of PHP like "php53-*" and "php7-*"
in the past to support both backward compat and recent code.

However, commercial distribution support after a PHP version is EOLed is
driven either by security concerns or support requests by customers
having a specific issue.

That's why I asked what would be a good baseline. I think the baseline
should be something >=3D 7.0

We should not forget horde is not isolated and depends on a ecosystem of
utilities like SabreDAV, Pear, PHPUnit (for development) and a few
others. Current master of SabreDAV requires PHP 7.0. Latest release
requires PHP 5.5.
As of today, the horde base app runs on php 5.3 and up.

Horde main versions tend to live long.
