Replying to myself - maybe of interest to some.
Moodle 3.6.10 , PHP 7.0.33.0.9.7 : I have been able to install with success older versions of the filter_embedquestion and atto_embedquestion , specifically these two:
FILTER: Version build number
2019081600
Version release name
1.6 for Moodle 3.6+
ATTO plugin:
Version build number
2019073100
Version release name
1.3 for Moodle 3.6+
It is not possible to install report_embedquestion , however, as this add-on requires a higher version of the filter_embedquestion plugin, which in turn requires PHP 7.1 .
HTH.
