I found this: those fields are created and deleted: file e_user.php

    /**
     * The same field format as admin-ui, with the addition of 'fieldType', 'read', 'write', 'appliable' and 'required' as used in extended fields table.
     *
     * @return array
     */
    function settings()
    {
        $fields = array();
        $fields['field1'] = array('title' => "Field 1",  'fieldType' => 'varchar(30)',  'read'=> e_UC_ADMIN, 'write'=>e_UC_MEMBER, 'type' => 'text', 'writeParms' => array('size' => 'xxlarge'));
        $fields['field2'] = array('title' => "Field 2",  'fieldType' => 'int(2)',       'type' => 'number', 'data'=>'int');
        $fields['field3'] = array('title' => "Field 3",  'fieldType' => 'int(1)',       'type' => 'method', 'data'=>'str', 'required'=>true); // see below.

        return $fields;

    }

But deleting plugins detects UEF by $eufields .= $spacer.'plugin_'.$plug_vars['folder'].'_'.$eu['@attributes']['name'];

from plugin.xml

    <extendedFields>
        <field name="custom" type='EUF_TEXTAREA' default='0' active="true" />
    </extendedFields>

The field from plugin.xml is not visible in UEF, but it is not deleted either, so the setting during installation is respected for this field.

Other fields shouldn't be deleted when I set not delete plugin tables. From the code is clear that they are always deleted if they are in the settings method in e_user.
