svg的path能否实现真正的环形渐变？

如demo所示的svg实现的环形进度条，实际上未能完全实现环形渐变，本质还是水平渐变，环形度数超过250度，就会体现出水平渐变。svg能否实现环形渐变？就像css的conic-gradient一样。因为conic-gradient会产生锯齿，所以才使用svg来实现，渐变效果不太理想。关键代码

<div style="width:150px;height:150px">
  <svg width="100%" height="100%" class="progress" viewBox="0 0 100 100">
                <defs>
                    <linearGradient id="grad1">
                        <stop offset="0%" stop-color="#29D65A"></stop>
                        <stop offset="100%" stop-color="#b3eac3"></stop>
                    </linearGradient>
                </defs>
                <circle class="c1" cx="50%" cy="50%" r="45%" stroke="#eee" stroke-width="5" fill="none" stroke-linecap="round" stroke-dasharray="283"></circle>
                <path d="M 50 50 m 45 0 a 45 45 0 1 1 -0.08879722072777696 -2.825573378819097" fill="none" stroke="url(#grad1)" stroke-width="5" stroke-linecap="round"></path>
            </svg>
</div>
