Do you have any reference of the exact commit which removed such
compatibility ?
This does not give me any hint:
git log --stat src/core/qgsprojectfiletransform.cpp
Also, the methods of that class suggest there is conversion code
for versions as old as 0.8.0:
QgsProjectFileTransform::TransformItem
QgsProjectFileTransform::sTransformers[] =
{
{PFV( 0, 8, 0 ), PFV( 0, 8, 1 ),
&QgsProjectFileTransform::transformNull},
{PFV( 0, 8, 1 ), PFV( 0, 9, 0 ),
&QgsProjectFileTransform::transform081to090},
{PFV( 0, 9, 0 ), PFV( 0, 9, 1 ),
&QgsProjectFileTransform::transformNull},
{PFV( 0, 9, 1 ), PFV( 0, 10, 0 ),
&QgsProjectFileTransform::transform091to0100},
// Following line is a hack that takes us straight from 0.9.2
to 0.11.0
// due to an unknown bug in migrating 0.9.2 files which we
didn't pursue (TS & GS)
{PFV( 0, 9, 2 ), PFV( 0, 11, 0 ),
&QgsProjectFileTransform::transformNull},
{PFV( 0, 10, 0 ), PFV( 0, 11, 0 ),
&QgsProjectFileTransform::transform0100to0110},
{PFV( 0, 11, 0 ), PFV( 1, 0, 0 ),
&QgsProjectFileTransform::transform0110to1000},
{PFV( 1, 0, 0 ), PFV( 1, 1, 0 ),
&QgsProjectFileTransform::transformNull},
{PFV( 1, 0, 2 ), PFV( 1, 1, 0 ),
&QgsProjectFileTransform::transformNull},
{PFV( 1, 1, 0 ), PFV( 1, 2, 0 ),
&QgsProjectFileTransform::transform1100to1200},
{PFV( 1, 2, 0 ), PFV( 1, 3, 0 ),
&QgsProjectFileTransform::transformNull},
{PFV( 1, 3, 0 ), PFV( 1, 4, 0 ),
&QgsProjectFileTransform::transformNull},
{PFV( 1, 4, 0 ), PFV( 1, 5, 0 ),
&QgsProjectFileTransform::transform1400to1500},
{PFV( 1, 5, 0 ), PFV( 1, 6, 0 ),
&QgsProjectFileTransform::transformNull},
{PFV( 1, 6, 0 ), PFV( 1, 7, 0 ),

&QgsProjectFileTransform::transformNull},
{PFV( 2, 0, 0 ), PFV( 2, 1, 0 ),
&QgsProjectFileTransform::transformNull},
{PFV( 2, 1, 0 ), PFV( 2, 2, 0 ),
&QgsProjectFileTransform::transformNull},
{PFV( 2, 2, 0 ), PFV( 2, 3, 0 ),
&QgsProjectFileTransform::transform2200to2300},
// A transformer with a NULL from version means that it should

// from any version and will take care that it's not going to
